Sonoff Quick Connector Set D1_1 — 34-piece quick wire connectors for electrical installations

Sonoff quick-connector set D1_1 (34 pieces) provides compact, reusable quick wire connectors for fast, tool-free joining and disconnecting of electrical wires in control, lighting and smart home installations. The set is intended to simplify wiring tasks where reliable temporary or permanent connections are required.

Advantages

The D1_1 quick connectors are rated for 250 V and 32 A, with red copper contacts for good electrical conductivity and a polycarbonate (PC) housing for mechanical durability. Each connector is small (9.1 x 39.3 x 14.5 mm) and compatible with a wide range of conductors, enabling safe connections without soldering, twisting or insulating tape.

Suitable for

• Control panels and electrical controls
• Lighting circuits and fixtures
• Smart home wiring and sensors
• Power supplies, motors and fans
• Outlet, switch and junction box connections

No soldering or additional insulating tape is required; ensure wires are stripped to the correct length and fully seated to achieve reliable contact.

Recommendations

Use within the specified rated voltage (250 V) and current (32 A). Select connectors that match the conductor type and cross-section: solid 0.5–4 mm² or flexible 0.5–2.5 mm². Inspect connections after installation and avoid exposure to environments outside the connector’s mechanical or thermal limits.
